The Northern Slimy Salamander, Plethodon glutinosus, is a species of terrestrial plethodontid salamander found through much of the eastern two-thirds of the United States, from New York, west to Illinois, south to Texas, and east to Florida, with isolated populations in southern New Hampshire and northwestern Connecticut. It is one of 55 species in the genus Plethodon and one of the first to be described of its cogeners. The salamander is called &#34;slimy&#34; because it is capable of excreting a sticky, glue-like substance from its skin. It is also sometimes referred to as the Viscid Salamander, Grey-spotted Salamander, Slippery Salamander, or Sticky Salamander, depending on which source is consulted. Due to its large geographic range, some taxonomic researchers have suggested splitting P. glutinosus into several distinct species, but this is not widely accepted.
